One is directly connected to the specificity of perceptual-cognitive expertise.
Considering (a) the relatively high number of studies examining the impact of physical load in non-athletes and (b) the specificity of perceptual-cognitive expertise, this review aims to provide detailed information on how athletes' perceptual-cognitive performance is influenced by acute physical exercise load and whether these effects differ between elite athletes and lesser skilled groups.
Since the impact of physical exercise on cognitive functioning is dependent on the characteristics of the physical exercise load (e.g., [1, 19]), and considering the specificity of perceptual-cognitive expertise [15], physical exercises were also classified as general or specific.
With these moderators in mind, and considering the specificity of perceptual-cognitive expertise (e.g., [15, 16]), the very small number of studies looking at the influence of different physical exercises on athletes' perceptual-cognitive performances is surprising since athletes have to combine these tasks with the specific physiological demands of their sport.
Further training is unlikely to enhance reliability in this case, but raises the question about the importance and specificity of relevant clinical expertise when selecting evaluators.
Alternatively, the cases were designed to cover a range of patient demographics and presentations and it may be that content specificity at all levels of expertise was responsible for some of the difficulty in discriminating between subject-groups.
Clearly, specificity is important in the context of expertise; however, we had to create broad categories in order to adequately summarize and combine results to provide an overview of the existing literature on the impact of different acute physical exercises on perceptual-cognitive performances of athletes.
However, specificity plays an important role in the science of expertise, both in understanding the limitations of perceptual-cognitive skill and in designing valid and reliable tasks to measure these qualities.
